Today, I had an Ethics and faith lesson with our school father (I go to an Anglican school) and he reminded me of an argument that I have been hearing for a long time. It’s actually three arguments, the first is, “Why is there something rather than nothing?”, the second is “Why do humans and other animals exist?”, and the third is “The earth is so beautiful, it can’t have happened by chance.”His answer to all of these questions is that there must be a supreme being or god who designed it intentionally for us, so it is beautiful and appealing to us. All of these arguments are of the kind ‘post hoc, ergo propter hoc’, and I have covered that in my brief of logical fallacies which can be found on the home page. I will answer these questions in my blog post today.
The first argument, “Why is there something rather than nothing?” This can be explained easily with chance. Simply, there is only one way in which there is nothing, null and void, but there are infinite ways in which something can exist, and seeing that 1/∞ = 0, (1/2 = 0.5… 1/10 = 0.1… 1/100 = 0.01) it just has to happen. No god is needed to explain everything because something must happen. It would be more surprising if there was nothing, and we would need to have a god to explain it, but there would be nobody around to ask the question, and that leads me to the next argument.
“Why do humans and other animals exist?” This is the second question asked by my Ethics and Faith teacher. He says that there must be a god who put life on a planet to explain this. There isn’t a need for this. It has been estimated that there are about 150 billion galaxies in the known universe. There are also anywhere from 10 million to 200 billion stars in a galaxy, I will take an average of 100 billion stars in a galaxy. That comes out at about 15 000 000 000 000 000 000 000 (15 000 billion billion stars.) That means about that many rocky planets, so that means a lot of possibilities for life. The odds are slim for an individual planet, but with that many dice-rolls 10 heads in a row is not un-common.Once there is some sort of self-replicating organism, then evolution takes over and does its thing.
Now, the third argument. “The world is so beautiful, this can’t have happened by chance.” First of all, yes there is beautiful things like rainbows and forests and mountains, but there are equally bad things like some fish species or snakes or spiders and other animals which may kill you, not to mention all of humanities problems. There is as much beautiful stuff as there is not beautiful stuff. This is because the definition of beautiful is ‘the top 50% of things in the world on a scale of beautifulness’. There will always be beautiful things. But just for my teachers sake let’s try and explain why some things are so beautiful. Our subjective grading of what the most beautiful things are is taken from a data set of one.
Say the world was a little less beautiful than what it is, we would still think of the most beautiful things as ‘the most beautiful things’ and the least beautiful things as ‘the least beautiful things.’ If the world was a little more beautiful than what it is, we would still have the same titles for the most beautiful and least beautiful things. We get used to what is beautiful and what is not because we grow up in our world, not another world.
What I’m essentially saying is that things are the way it is because they are the way they are, and we wouldn’t be asking these questions if the world was different. I will leave you with a quote from Richard Dawkins, “The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity.” Richard Dawkins, Evolutionary biologist, skeptic, atheist and author of some note.
